VENDING MACHINE.

Application filed May 31,

This invention relates to a vending machine, the general object of theinvention being to provide a plunger having a slide at one end thereoffor moving articles from a container into a delivery chute with coinoperated means for holding the plungeragainst movement until a coin isinserted into the device.

,Another object of the invention is to provide spring means forreturning the plunger to normal position and to provide a money drawerfor receiving the coins from the plunger after the plunger has beenmoved to its innermost position.-

This invention also consists in certain other features of constructionand in the combination and arrangement of the several parts, to behereinafter fully described, illustrated in the accompanying drawingsand specifically pointed out in the appended claim.

In describing my invention in detail, reference will be had to theaccompanying drawings wherein like characters denote like orcorresponding parts throughout the several views, and in which Figure lis a front view of the invention.

Figure 2 is a section on line 2-2 of Figure 1.

Figure 3 is an enlarged sectional view showing one of the plungers inpartly projected 1 position.

Figure 4 is a ure 3.

Figure 5 is a section on line 55 of Figure 3.

Figure 6 is a view of the coin operated spring.

In these views, 1 indicates a casing, which is made with a narrow upperpart and a. wide lower part, the upper part being provided with atransparent front 2 and a mirror 3 and a hingedtop 4 which may be lockedby any suitable form of lock, shown at 5. The articles to be vended areplaced in the guideways 6, the front portions of which are formed by therods 7 after raising the top 1. A horizontally arranged plunger 8 isassociated with each guideway and each plunger has on its inner end aframe which consists of a cross piece 9 and a yoke 10 which has itsbight spaced from the front edge of the cross piece to form a receivingspace for the lowermost article in the guideway. By pushing the plungerinwardly the article A, shown in this instance as perfume section online 4.--4 of Fig- 1924. Serial No. 717,100.

bottles, is moved from the bottom of the guideway over the upper end ofa chute 11 which is so arranged-as to cause the article to pass to'apocket 11' at the front of the casing where it may be picked up by thepurchaser. A spring 12 is arranged on the plunger and acts to hold thesame in its outermost position, said spring having one end engaging a.U-shaped guiding member 13 through the bight of which the plunger passesand which has its limbs connected a guiding means for the plunger and tothe top of which is fastened a spring plate 15 with its front end bentdownwardly, as at 16, to engage a shoulder 17 formed on the plunger,thus holding the plunger in its outermost position. The front end of thespring plate is located just in rear of a coin chute 18 formed in thetop of the wide part of the casing and with which a slot 19 in theplunger will register when'the plunger is in its outermost position Thebottom of a recess 20 acts as a support for the coin when engaging theslot 19 and a coin opening 21 in the partition 22 is arranged adjacentthe recess so that when the plunger is moved forwardly the coin willroll along the bottom of the recess and drop into the opening 21 andthus pass into a money drawer 23 located under the partition. As

the coin moves along the bottom of the with a stationary part 14 whichalso acts as recess it will strike the depending part 16 t of the plateand raise the sameout of-engagement with the shoulder on the plunger topermit the plunger to be forced inwardly to its entire extent and thustake an article from the guideway and-deposit it into the three chute11. The drawing shows plungers and three guideways for supporting threerows of articles with themoney drawer .22 arranged to receive the coinsfrom all of the plungers, though it will of course be understood thatthis arrangement can be varied to suit conditions. The articles can beseen through the transparent face of the casing.

From the foregoing it will be seen that it is simply necessary to placea coin of the desired denomination in a coin chute so that this coinwill rest upon the bottom of the recess 20 in the partition 22andproject from the'slot 19 in the plunger. Then by pushing upon the outerend of the plunger the coin will be forced into engagement with thedepending part of the spring 7 plate so as to raise said plate out ofengagement with the shoulder on the plunger to permit the movement ofthe plunger to be continuedand thus move an article resting upon theinner end of a partition and fingenis released from the plunger .the

spring 12 will return the plunger to its outermost position and thedepending part in' the spring plate will-drop in rear of the shoulder onthe plunger and thus prevent another inward movement of the plungeruntil another coin has been placed in the coin chute. The coin will beforced through the opening 21 into the money drawer as the plunger movesinwardly under the action of gravity and the pressure of the springplate.

It is thought from the foregoing description that the advantages andnovel features of my invention will be readily apparent.

I desire it to be understood that I may make changes in the constructionand in the combination and arrangement of the several parts, providedthat such changes fzlill within the scope of the appended 0 mm.

What I claim is A vending machine of the class described comprising acasing having a guide way therein for containing the articles tobevended, a stationary horizontal guide member, a U-shaped guide havingits end attached to the stationary guide, a plunger movable through theguide and intermediate portion of the U- shaped guide, a chute in thetop of the easing, said plunger having a slot adapted to be normallyaligned with the chute, a partition in the casing below the plunger,said partition being formed with a recess aligned with the chute andfurther provided with an opening out of alignment with the chute,yieldable means for retaining the plunger in an inoperative positionincluding a coil spring upon the plunger between one end of thestationary guide and the intermediate portion of the U-shaped guide,means preventing movement of the plunger against said spring. said meansbeing released through movement of the plunger and means carried by theplunger for removing the arstationary ticles from the guide way one at atime upon movement of the plunger in one direction.

In testimony whereof I aflix my signature.

ROBERT M. WILLIAMS.
